Change relevance based on a certain number response

Hi all,

I am making a form with the following three questions:

  1. Total number of adult patients attending the facility
  2. Total number of child patients attending the facility
  3. Total number of patient attending the facility.

Question 3 will be automatically calculated based on the previous two questions. For question 1 & 2, I have added a note to say that if the number is unknown, they should enter '999'. Is there a way I can void the third question if 999 is entered for question 1 and/or 2.

Many thanks!


Hi @faran_d

in the relevant column, this test will do what you want (both question 1 and 2 must be different from 999) :

${question_1} != 999 and ${question_2} != 999
